Zithromax is part of a class of drugs called macrolides. It decreases bacteria's ability to make protein and affects peptide activity, both of which the bacterium needs to live.
By affecting the protein and peptides of bacteria, Zithromax helps to stop bacteria from continuing to live and cause infection in the body.
Some general considerations for when and how to take Zithromax include:
- Zithromax comes as a tablet or liquid suspension. Zithromax is usually taken once daily, depending on your healthcare provider's instructions.
- Zithromax can be taken with or without food.
- Drink a full glass of water with each dose.
- Zithromax should be taken at the same time each day to maintain an even level of medicine in your system.
- For Zithromax to work properly, you have to take it as prescribed. Make sure that you complete your entire prescription of Zithromax, even if you start feeling better. This will ensure that the infection is completely treated.
- Never take outdated Zithromax. Taking any outdated medication may cause serious problems because the intended effects often change after expiration.
The immediate-release suspension or tablet may be taken with or without food. If you suffer from an upset stomach while taking either of these forms of Zithromax, try taking them with food or milk.
Zithromax extended-release suspension (Zmax™), however, works the best if taken either one hour before you eat, or two hours after you have eaten. If extended-release Zithromax is taken too close to meals, Zithromax will not be absorbed as well and may not produce maximal effects.
